Hi,

This is related to espeak, not phonemizer. Here its output compared to the one of espeak-ng-1.50:

$ echo "aneinander" | phonemize -l de -b espeak --with-stress
ˌan1aɪnˈandɜ
$ echo "aneinander" | espeak-ng -qx --ipa -v de
ˌan1aɪnˈandɜ

So we have a strict equivalence. If you think this is a bug please forward it to the espeak-ng repo.
